In DeployHQ, you can upload your own custom keypair to one or more projects. This might be useful if you have a number of different projects all deploying to the same servers.
To upload a new key pair, head to the Configuration page in any project, then below the current public key you'll find a link to upload a private key. Click this link, then upload your the private key by pasting it in the dialog, then clicking Upload Private Key;
Please note that any previously connected services, in particular your repository will require updating if you upload a custom key, as the same SSH key pair is used to connect to both your repository, and any configured servers in your project.
